Fig. (3) Comparative plots of a) percent increases in peak NAFX vs Pre-therapy NAFX and b) percent increases in LFD vs pre-therapy LFD during fixation of far targets with contact lenses, with acetazolamide, and during convergence at 60 PD. Curves shown are the estimated percent increases in peak NAFX and LFD for the tenotomy and reattachment (T&R) procedure.
